I ran into a problem some time ago and tried to talk it out between Z-stuff,Lionel, and Gargrave switches. The problem is Lionels command control crane hits the DZ-1000 and the new DZ-2000 machines. No matter if its Gargraves track or lionel track with the switch machine shimed to the correct hieght it wont work. Of course you know lionel denies everything and is no help at all. Gargraves at least pointed me in the direction to go for help which is Z-stuff. So I wrote to Z-stuff asking him a fix for the problem. He tells me he cant fix it cause he cant see the problem and isnt going to purchase a crane to look at the problem. Then he wants me to send my crane and boom car to him with me paying the shipping both ways knowing UPS dont handle fragile items well i of course told him no way. I asked him why he couldnt just go to a hobby shop near him and simply look at a crane. He tells me he dont want to. He tells me to trade and upgrade the dz-1000 for a fee. I asked him if he knew if it would work. He says he doesnt know for sure. So I asked him why I would want to go through my layout and change the switch machines when he doesnt know if it will fix it. The guy tells me he needs pictures of the problem. So I take some pictures or the problem and send them to him. He tells me it is my fault that train wont go by the switch because i mixed the lionel and the gargraves track together and shimed the dz up way to high but i told him its the same problem as with just gargraves track and a gargraves switch. He tells me no theres no problem and I should go through my whole layout and change the track to Gargraves cause it works. So I had some gargrave track laying around and did a set up with that and the switch machine and still have the same problem and so i sent him some pictures of it with an idea to fix the problem with a different sp
